To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
My son read the first book in this series and he asked for all of them. This is the second one in the series. The third one will be released later this year. I am going to preorder it. When you find a series that an eleven year old asks for you know it is an amazing series.
